During the spring sale at a store, a sweater was marked down from $50 to $20. By what percent was the sweater decreased? Group of answer choices

A. 60%

B. 50%

C. 30%

D. 150%

Based on the original price and the price the sweater decreased to, the percentage discount was 60%.

The percentage reduction can be found as:

= (Original price - Discount price) / Original price x 100%

Solving gives:

= (50 - 20) / 50 x 100%

= 60%

In conclusion, the correct answer is option A.

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
